Title: Method of preventing and, if need be, removing obstructions in the flushing-air passages of the drill pipe of drilling machines
Inventor: HAUSHERR HEINRICH-RUDOLF
IPC: E21B21/08
Filed: 1982-08-07
Abstract: To prevent obstructions from forming in the flushing-air passages of the drill pipe of drilling machines, it is proposed according to the invention that any pressure increase in the compressed air and/or any pressure drop at the drilling motors (3) be detected by means of adjustable pressure-measuring devices (13) and transmitted to control devices superimposed on the electro-hydraulic servo valves, which control devices control the pumps in such a way that a minimum value "0", possibly even a minus value, results. Pneumatic pressure intensifiers (14) are arranged parallel to the compressors (8), in which arrangement any pressure increase in the compressed air in the flushing-air passages (6) and/or any pressure drop at the drilling motors is detected by means of adjustable pressure-measuring devices (13) and transmitted to control gear (16) for controlling the pressure intensifiers (14). By means of adjustable pressure-measuring devices (15), any pressure increase in the compressed air in the flushing-air passages (6) and/or any pressure drop at the drilling motors is detected and transmitted on the one hand to control devices superimposed on the electro-hydraulic servo valves, which control devices control the pumps in such a way that a minimum value "0", possibly even a minus value, results, and on the other hand to control gear (16) for switching on pressure intensifiers connected in parallel with the compressors (8). <IMAGE>

Title: Push-button switch with switching hysteresis
Inventor: HECKING WILLI
IPC: H01H35/38
Filed: 1982-08-07
Abstract: A piston (22) rests on a fixed stop (24). A plunger (26) is guided in the piston (22) and rests, under the influence of a spring (46) by means of a collar (44) on the piston (22). If a maximum pressure is exceeded, the plunger moves upwards, and if the pressure is less than a minimum pressure, the plunger (26) and piston (22) move downwards. A spring buffer (46) having a spring (48) is seated between the plunger (26) and the switching pin (14) of the microswitch (12). The spring (48) transmits the retaining force rather than the switching force for operating the microswitch (12). Pressure-dependent switching with a large switching hysteresis is thus achieved. <IMAGE>

Title: Insulating element for heat insulation of outer corners of outer masonry walls
Inventor: KOCH GERO
IPC: E04B1/78
Filed: 1983-04-19
Abstract: In structural engineering, there is no known special heat insulation for outer masonry walls which is restricted to the outer corner. The insulating element fixed in the corner on the inside serves as a heat-flow barrier. The interruption of the heat flow in the diagonal direction and the heat-flow compression in the adjoining wall material, which is moderate owing to the depth of the insulating element, cause the drop in the internal surface temperature to be reduced to a fraction. The outer corner as a structural weak point is considerably improved in its energy effect and in relation to the risk of mould formation.

Title: Hoeing machine for working the planting gaps of cultivated plants
Inventor: NUESSL ALFONS DIPL ING
IPC: A01B39/18
Filed: 1983-08-19
Abstract: This invention describes a "hoeing machine for working the planting gaps of cultivated plants". The agricultural appliance is employed in the cultivation of root crops. Mainly for sugarbeet and cabbage plants. The mode of operation is as follows: the plants of a size of 4 cm to 25 cm, standing in rows and with a final spacing, are sensed by a light barrier which slides over the ground at a distance of 3 cm. A displacement sensor driven by the supporting wheel generates 1000 pulses per metre of path covered. These signals are processed in a computer. It determines the travelling speed, the plant spacing, the plant width and the time of use of the hoeing unit. The hoeing unit, consisting of a hoeing knife, of a four-bar mechanism and of a lifting cylinder, is driven hydraulically. By means of this appliance, the planting gap can be cleared of weeds mechanically and the ground loosened.

Title: Shuttering brick for a cob wall and process for its production
Inventor: WEIL THOMAS
IPC: E02D29/02
Filed: 1983-10-28
Abstract: For producing a cob wall with permanent shuttering, a shuttering brick (3) designed as an elongated angle section piece is provided, the essentially plate-shaped legs (3, 5) of which, connected to each other in their longitudinal direction, run approximately at right angles to each other. The outside of the angle of one of the two legs (5) defines a bearing surface (9), by which the shuttering brick (3) is laid on the level upper side (13) of the cob wall (1), if appropriate with a joint-forming bed (15) interposed. The free longitudinal edge of the second leg (7), facing away from this bearing surface (9), forms a screeding edge (11) which is parallel to the bearing surface (9) and along which the cob wall course filled in and rammed between two rows of fitted shuttering bricks (3) can be screeded, for example by means of a screeding rule. The shuttering bricks (3) form a fair face or serve as lathing for the wall plaster. To allow for shrinkage, in the region of the bend on the outside of the angle of the shuttering brick there may be a flute, into which the shuttering brick lying respectively underneath can penetrate. <IMAGE>

Title: Design of stackable unencapsulated power semiconductors for evaporative cooling
Inventor: HAHN KURT
IPC: H01L23/427
Filed: 1983-11-18
Abstract: In the case of an arrangement of an unencapsulated power semiconductor wafer (1) which is immersed in an evaporative cooling liquid and which is radially fixed between two heat dissipaters (2, 3), which serve as anode-side and cathode-side connections, by three axially extending plastic holding devices and is axially clamped by means of insulated tie bolts (7), the intention is that many of these devices can be pressed together to form stacks but that an adequate surface of the heat dissipaters (2, 3) can nevertheless be provided for evaporative cooling without film boiling. For this purpose, the heat dissipaters (2, 3) are provided with spacing protrusions (8) on the side remote from the power semiconductor wafer (1). The clamping force (P) of the tie bolts (7) is transmitted to the power semiconductor wafer via said spacing protrusions (8). The plastic holding devices are designed as insulating studs (9) which are embedded in one of the heat dissipaters (2 or 3) and which form a snap holding device for the power semiconductor wafer (1) so that a compact and simple assembly is achieved at the same time. <IMAGE>

Title: Method for roll cooling in a cold rolling mill
Inventor: SCHNEIDER MANFRED DIPL ING
IPC: B21B37/32
Filed: 1984-07-07
Abstract: A method is indicated for roll cooling in a cold rolling mill, in which, to determine a coolant quantity distribution, it is possible to adjust the coolant quantity zone-by-zone along the roll axis. Automation of the emulsion distribution, previously input by hand via an illuminated keypad, is proposed such that the flow rate in each cooling zone i is controlled by a flow control circuit, the flow rate setpoint values Qi of which are corrected by means of an empirically determined relationship Qi = Qi (qF) where qF is the thermal power density in the roll, which density is calculated continuously on the basis of measurable process variables and roll setpoint values. A suitable calculation equation is given by  qF = v . P . (1 + P/c . h)/r where v is the roll speed, P is the rolling force, h the pass reduction, r the work roll radius and c a constant. The relationship Qi = Qi (qF) can be determined in preliminary tests, in which the coolant distribution is adjusted as before by input via an illuminated keypad, the required measured values being recorded continuously during the preliminary tests. <IMAGE>
